Sometimes I am offered something but because I'm just a beginner I don't know what verb they used.

I know the proper way to say "no" is to answer with the negative form of the verb the other person used, that いいえ alone is too abrupt.

Also from experience I know that the words in some languages meaning "want" or "need" might have nuances that make them inappropriate.

Usually I want to say "I don't need it" or "I don't want one" in a shop that offers me a bag or a drinking straw or disposable chopsticks. But this evening while exploring Naha I discovered I had wandered into the red light district and was offered a "nice girl"!

How should I correctly express "no thanks, I don't want one" when I didn't hear the verb used?

Their usage overlaps (after all, they all mean "no, thank you" in some sense). 結構です is quite formal and いいです probably the most common option, closely followed by いらないです. (The forms based on いらない are more direct.) If you want to be informal, use いい or いらない.

The first reaction "No" is usually voiced as いや and can be used with all the options above, e.g. いや、いいです. いいえ can be used in いいえ、結構です.

Caveat. Although いいです is understood to mean "No, thank you", いいですね would usually be interpreted to mean "Yes, please".

いい and 結構 both mean fine, I think we can say the latter is 丁寧語 for いい、the caveat is that you have to get the intonation correct.

@Tim It might be helpful if you explained a little bit about the proper intonation.

I am not sure how put it into words or I would (especially as the NHK 発音アクセント辞典 only gives one way of saying it (ケッコウ{HHLL}, 〜な)). However, also, when using the expression I am careful to give the correct NVC.
